Introduction
This is an early project based on SIMD data that I’m using to try and learn R. I intend to explore the package ‘ggplot2’ to practice a set of skills I’m attempting to learn through a combination of DataCamp courses, RStudio ‘Cheat Sheets’ and twitter.
Early progress
Initially I used map cordinates given by Ordinance Survey to find the centre of any KA27 postcode on a map. (KA27 being the prefix or ‘postcode area’ that denotes all Aran Island postcodes).
I then read the coordinates into sf with st_as_sf(), and plotted over a shape file map of Arran; over the SIMD data zones, as well as the section of coordinates contained in one data zone/
Coordinate plots
With the postcodes sorted, I then wanted to relate some other information about these areas. I used SIMD ‘DataZone boundraries’ and plotted their ERSI Shapefiles using ‘geom_sf.’ First the data zones onto the island. Then I coloured/labelled the individual data zones. Having worked that out, I wanted to show some health data about the zones. I overlayed ‘percentile’ data about the areas for 2016.

Then after faffing about with individual shape files for every year, (The data zone labels changed after 2012), I did the same for all the SIMD data periods and used facet_wrap to plot them all together.
Percentile Facet_wrap
Combining the coordinate and SIMD data, I’ve summarised one of the zones (S01004372) below.

### S01004353/S01011177 
### S01004352/S01011176 
### S01004351/S01011175 
### S01004350/S01011173 
### S01004349/S01011172 
The next steps will be to overlay this data over a map using leaflet.
The overall aim of this project will be to create an easy template by which a user with no prior programming knowledge can create interactive graphs by overlaying some form of data attributed to a postcode alone.
